Anyone else come across this, desk output keeps randomly and momentarily ducking for no reason. No fader movement either.

At a loss here.

Check the inserts for all channels/groups that seem to be ducking. There may be a multiband or dynamic EQ happening with another source in the sidechain.

It could also be that the channel/groups have a ducker set up (found in the gate section), but it is side chained to another source. That could explain why it ducks “randomly”.
